Well Im diabetic and over the years have had many a hypoglycemic dip and I wouldnt class myself as having irrational anxiety attacks or obsessive thoughts or fears ..... however in the middle of having one of these hypoglycemic dips it is quite common to only be focused on getting glucose back into the body and if the attack id bad enough it can be almost obssessive like, oh and it can make you become quite stroppy even though you don't realise it. Not sure of this is of any use or help to you lol
